What should I do about a fence that's leaning onto my neighbour's property in Surrey?

A leaning fence needs to be assessed quickly — if it's crossed the property line or is at risk of falling, you have both a neighbourly obligation and a potential legal liability to address it.

The first step is to determine why the fence is leaning. The most common cause in Surrey (and across Metro Vancouver) is post failure — either the post has rotted at or below grade, the concrete footing has heaved or cracked, or the post was never set deep enough to begin with. Surrey's clay-heavy soils in many neighbourhoods retain moisture exceptionally well, which accelerates rot at the post base even on treated wood. Pull back any soil or vegetation at the base of the leaning posts and probe the wood with a screwdriver. If it sinks in easily, the post is rotted and needs full replacement, not just straightening.

If the posts are structurally sound but the fence has shifted due to soil movement, frost heave, or a vehicle impact, a contractor may be able to re-plumb the posts and re-brace them without full replacement. This is the best-case scenario and typically costs $150–$400 per post depending on access and how much work is involved. However, if the posts are rotted — which is the more common finding on fences over 10 years old in Surrey's wet climate — you're looking at post replacement or a full fence rebuild.

Sorting Out the Property Line First

Before any repair or replacement work begins, confirm where the property line actually sits. A fence that has leaned over time may have shifted its footprint, and this is a good opportunity to reset it correctly. If you don't have a recent survey, the BC Land Title Office has records you can reference, but for precise placement, a licensed BC Land Surveyor is the authoritative source. Surveys cost $1,000–$3,000 in Metro Vancouver but prevent boundary disputes that can cost far more to resolve. Surrey has seen significant infill development and lot subdivision in recent years, so older surveys may not reflect current registered boundaries.

Talking to Your Neighbour

If the fence sits on or near the shared property line, your neighbour has a stake in this conversation. Under the BC Property Law Act, boundary fences are generally a shared responsibility — but the specifics depend on who built the fence, whether there's a written agreement, and what condition it's in. Have an honest conversation before hiring anyone. Many neighbours are willing to cost-share on a replacement fence, especially if the existing one is failing. Getting any cost-sharing agreement in writing before work starts protects both parties.

What Surrey's Bylaws Say

Surrey's standard residential fence height limits are 1.83 metres (6 feet) in rear and side yards and 1.22 metres (4 feet) in front yards. A standard repair or like-for-like replacement generally does not require a building permit, but if you're changing the height, style, or location of the fence, confirm with Surrey's Building Division before proceeding. Surrey also has specific sight-line requirements for fences on corner lots near driveways — worth checking if your property is on a corner.

Practical Next Steps

Call BC One Call at 1-800-474-6886 before any post holes are dug — this is free, legally required in BC, and takes 3 business days to process. Surrey has extensive buried utilities in established neighbourhoods and new subdivisions alike. Once you have a locate, get two or three quotes from fence contractors who will assess the posts individually rather than immediately pushing for a full replacement. Ask each contractor specifically whether the posts are rotted at grade or below, and request that any replacement posts be set with a gravel drainage bed (4–6 inches of clear gravel below the post base, concrete above) — this is critical in Surrey's wet soil and significantly extends post life compared to concrete alone.
